This isn't a major site change, but it does have a lot to do with how people participate in the site ... We've changed the way comments display under a post.
They are no longer "threaded," which means direct replies to a previous post no longer appear under the comment being replied to. While the intent of that format is to make conversations easier to follow, it never really works that way.
The "old school" way of displaying comments on posts is in a flat list with the oldest comments on top, newest on the bottom. That's what we're doing now.
